Description

The TL7660CDR is a switched-capacitor voltage converter IC manufactured by Texas Instruments. It is designed to invert input voltages, effectively converting a positive voltage to a negative one of nearly equal magnitude. This makes it useful in applications where a negative supply voltage is needed but only a positive supply is available. The TL7660CDR operates with an input voltage range of 1.5V to 10V. It features a low quiescent current, typically around 120 µA, making it suitable for battery-powered applications.
Key features include a simple implementation that requires only two external capacitors, a wide operating temperature range, and the ability to achieve high efficiency due to its low power consumption. Additionally, the device typically supports a current output of up to 20 mA. The TL7660CDR is commonly used in applications such as operational amplifier voltage supplies, portable instruments, and any systems where minimal external components are desired for creating dual power supplies from a single supply voltage.

Equivalent

The TL7660CDR is a charge pump voltage converter IC. Equivalent products include the MAX1044, ICL7660, and LTC1044. These ICs perform similar functions, offering voltage conversion (e.g., positive to negative voltage), and are often pin-compatible. When selecting a replacement, ensure compatible specifications such as input voltage range, output current, and operating temperature. Always refer to the datasheets for confirmation on compatibility and performance.
